I have been a stickler about keeping power cables away from signal cables...on equipment ?

What I am finding very interesting, and to some extent, disturbing, is how close the power IEC inlet or power cable, is designed so close to the speaker or input / output terminals of amplifiers / gear. Many of my Hafler, Bryston and Citation amplifiers had / have this arrangement, and many of these newer and smaller chassis class d amplifiers have this arrangement. I have actually rewired ( or had rewired by a tech ) a different path separating the power line to the audio line within the chassis, and hearing a cleaner background when listening to music through these products afterwards. I am finding this to be the case, looking at photos of some other gear as well. I also believe, power switches and it's wiring, should be designed at the rear of a component, for the reduction of ac related noise, even though it might be an inconvenience with it's daily operation. Just as an aside.....I keep my gear on 24 / 7, unless I am on an out of town trip. Your thought ? Enjoy, be well and stay safe. Always, MrD.

I'd venture to say that it's all due to design, packaging and costs. Some makes will go so far as to put shielding, covers and walls inside an amp to segregate sections so they pollute each other. 

It's sad to think that someone will go to the trouble of designing something nice and then when they figure out how to package it, they just cram it all in without regard to placement and interaction.

Wasn't it normal for some vintage gear makes to have the inputs on the side of their integrateds and receivers? I wonder what the reasoning was behind that.

All the best,
